The best set I've used is this:
Jester (Gourgeist-Super) (F) @ Leftovers
Ability: Frisk
EVs: 252 HP / 4 Atk / 252 Def
Impish Nature
- Phantom Force
- Leech Seed
- Substitute
- Will-O-Wisp
Goodness, this thing is amazing on semi-stall. SubSeed coupled with Lefties for passive recovery, WoW to make physical attackers whimper at your AMAZING defensive bulk even MORE, and Phantom Force to rack up the residual damage AND your recovery damage. Phantom Force with this set is absolutely golden.
